Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world. About 1C of total warming. Second chart: about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability. Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases. About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Who Gets to Block the Sun? Stardust sold geoengineering to investors. Now it needs to sell it to the public. (www.theatlantic.com)

an American-Israeli company

Fuck that

Stardust told me it has no outdoor tests planned and that it will not conduct any until relevant regulations are established; its framework proposes extensive laboratory testing and computer modeling before beginning small-scale testing that they will “tightly monitor,” eventually scaling up to dispersing the particles across a wider area.

That's good at least maybe

I dgaf where it's from, can we please just stop with global shit like this that inevitably will benefit only a few rich?

Yeah, I have zero trust that they would test it in secret

Yeahhhhhhhhh \Or just somewhere with super lax regulations

I'm sure some authoritarian leader would welcome them with an open wallet.
